Readily Biodegradable Sodium Acetate | Carbon Source for Denitrification
Sodium Acetate | Denitrification
High-reactivity sodium acetate carbon source designed to enhance biological denitrification efficiency in low C/N wastewater treatment systems.
What Is Sodium Acetate for Wastewater Treatment?
Sodium Acetate is a highly bioavailable external carbon source widely used in biological wastewater treatment to support denitrification processes.
Unlike complex organic carbon sources, sodium acetate can be directly absorbed and metabolized by denitrifying bacteria without prior hydrolysis, enabling fast microbial activation and stable nitrogen removal performance.
As a professional sodium acetate supplier for water treatment applications, we offer both powder and crystalline forms suitable for precise dosing and flexible operation. Sodium acetate is especially effective in low C/N ratio wastewater, cold-weather operation, and treatment systems facing total nitrogen (TN) compliance challenges.
Direct Microbial Utilization
Low-molecular acetate ions enter microbial metabolic pathways directly, accelerating denitrification reactions.
Stable and Predictable COD Release
Allows accurate dosage calculation and minimizes the risk of effluent COD fluctuation.
Strong Low-Temperature Adaptability
Maintains biological activity in winter or low-temperature operating conditions.
Clean Degradation Pathway
Decomposes into CO₂ and H₂O without secondary pollution or toxic by-products.
Flexible Solid Forms Available
Powder and crystal options support different storage, dissolution, and feeding systems.
